如何計算 SQLite 中小計列的總計

Question

我正在嘗試在 C# 中獲取摘要報告。 我使用 SQLite 數據庫來存儲我的數據。 在給定的圖像中，我計算了每個位置的總價。 請幫我找出最后一行中 TotalPrice 列的總計，如圖所示。 謝謝你。 請檢查圖像

這是我的查詢。

  SELECT Job_Mst.JobCode
    ,Location_Mst.LocationName
    ,sum(JobTransaction.TransactionPrice) AS TotalPrice
FROM Job_Mst
LEFT JOIN JobTransaction ON Job_Mst.JobId = JobTransaction.JobId
LEFT JOIN Location_Mst ON Location_Mst.LocationId = Job_Mst.LocationId
WHERE JobTransaction.DATE BETWEEN @firstDate
        AND @secondDate
GROUP BY Job_Mst.LocationId

I am fetching data from 3 tables..

檢查一次

WITH Totals
AS (
    SELECT Job_Mst.JobCode
        ,Location_Mst.LocationName
        ,sum(JobTransaction.TransactionPrice) AS TotalPrice
    FROM Job_Mst
    LEFT JOIN JobTransaction ON Job_Mst.JobId = JobTransaction.JobId
    LEFT JOIN Location_Mst ON Location_Mst.LocationId = Job_Mst.LocationId
    WHERE JobTransaction.DATE BETWEEN @firstDate
            AND @secondDate
    GROUP BY Job_Mst.LocationId
    )
SELECT *
FROM Totals

UNION ALL

SELECT 'Total'
    ,''
    ,SUM(TotalPrice)
FROM Totals
